Hello,

1. The chromosomal theory of inheritance was given by Boveri and Sutton in the early 1900s. It is the fundamental theory of genetics. According to this theory, genes are the units of heredity and are found in the chromosomes.

Chromosomal Theory of Inheritance came into existence long after Mendelian genetics.

2. In linkage, two or more genes linked together are always inherited together in the same combination for more than two generations, whereas in recombination the genetic material is exchanged between different organisms which leads to the manufacture of offsprings with the combination of traits.

thank you.
